What is a GFS file?

GFS files mostly belong to 7-Zip. GFS files are not a single standard type but are used in several different applications.
Key uses:

Game Data Archive: Some GFS files are game archives. For example, the Skullgirls game uses a GFS file to store game data with the Reverge Package Tool, and similar files are found with the Reverge Engine.

Geospatial Data: Other GFS files hold geospatial feature data and CityGML GML Feature Class lists. These files work with GeoServer. Visit GeoServer for more information.

Game File System Container: A number of GFS files act as file system archives for games. Some of these can be opened with archive utilities like 7-Zip.

Geode Statistics: A few GFS files are used by GemFire to store internal statistics. More details are available at Apache Geode.

Ransomware Encrypted: In some cases, GFS files result from ransomware encryption (associated with Rumba) and are not easily accessible.

Financial Data: Rarely, these files serve as global financial system files, viewable with a specialized GFS Viewer from Gaming Laboratories International.

Opening and viewing a GFS file

Identify the source application (game engine, geospatial software, archive extractor, etc.).

If it is a game archive or file system container, an extraction tool like 7-Zip may work.

If it is geospatial data, use GIS software that supports GeoServer formats.

Encrypted files might need special decryption tools or professional help.

FilExt.com tip: Understanding the origin of your file is key to choosing the proper software.

How to open a GFS file

You need a suitable software like 7-Zip to open a GFS file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your GFS file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a GFS file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert GFS files:

7-Zip
See the previous paragraphs to learn more about the main application. GFS files are often referred to as 7-Zip games because this type of file is primarily created or used by this software.
GGFileSPlit (File Fragment) by GGNetworks
One of a set of fragments in a set that represents the split original file. The identifying characters used for this association are - Hex: 3C 47 46 53 53 74 75 62 20 5F 53 74 75 62 46 69 6C 65 50 61 74 68 3D 22, ASCII: <GFSStub _StubFilePath=".

Office Groove (Partial Download File) by Microsoft Corporation
Office Groove is a collaboration software program that helps teams work together dynamically, even if team members work for different organizations, work remotely, or work off-line. When downloading a file new files display in the file sharing workspace with a download indicator, and are listed with the file type Groove Remote File. The file extension .GFS is appended to the file name until the download is complete (i.e., the file has a double extension; the original and the added .GFS).

GFS file format:

If you can determine the file format, the associated program can also be determined. The file format can be determined based on the file extension and the signature (the first few characters of a file). However, different programs can use the same file extension. Furthermore, a file extension can be renamed incorrectly and double-clicking on it will then display an error when it is opened. So you need a detailed analysis of a file to find out the format and the associated program. Below you will find our evaluation of the GFS files:

An GFS file includes different formats for the applicable programs. The file formats most commonly found in GFS files are:

45% of all GFS files have the same signature 00 00. The content consists of illegible binary data, which can only be read and interpreted by the associated programs. GFS files are between 5 MB and 340 MB in size. The file type is relatively new. Certain words are almost always found in the files, such as Reverge Package File, temp and beowulf. Examples of file names are characters-art.gfs or sprites.gfs. These files are attributed to characters, music, textures and levels.
20% of all GFS files belong to GML Feature Class List. The files are using the common file format XML. The Extensible Markup Language (XML) is a simple text-based format for representing structured information: documents, webpages, data, configuration, books, transactions, invoices, and much more. XML defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. These files are plain text, which means they can be viewed with any text editor such as Windows Editor, Nano for Linux, and TextEdit for macOS. A typical file size is 600 bytes. Certain words are almost always found in the files, such as <GMLFeatureClass>, <GMLFeatureClassList>, ElementPath, Name, GFSStub _StubFilePath, _ShareObjectName and GeometryType. Such files sometimes refer to line, docx and dtad.

All other GFS files (35%) have no consistent format, frequently e.g. GFS and Reverge. Often described as artgallery, xlsx, storyart or intel. If you want to find out which format your GFS file belongs to, just click on the button "Choose your .gfs file to analyze".

How to solve problems with GFS files

Associate the GFS file extension with the correct application.
Update your software that should actually open container files. Because only the current version supports the latest GFS file format. Search, therefore, e.g. on the manufacturer website after an available 7-Zip update.
To make sure that your GFS file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
